Can optical fibres double as seismic sensors? Yes! Our work within the ALLEGRO project explores how state of polarization (SOP) variations in fibre-optic networks can be leveraged for earthquake detection and early warning systems. 📡🌎
🔬 How it Works:
Using commercially deployed fibre cables and IMDD transceivers, we have successfully:
✅ Detected and localized vehicle movements in Turin, Italy, with <100m accuracy using SOP variations. 🚗📍
✅ Developed a waveplate-based simulation model to better understand external stress-induced SOP alterations.
✅ Trained a Bi-directional GRU ML model on earthquake data, achieving 97% accuracy in detecting Primary waves (P-waves).
⚡ Key Findings:
🔹 By applying our method to real ground motion data from the Italian National Institute of Geophysics and Volcanology (INGV), we validated our approach for seismic event detection.
🔹 We are now expanding our research by treating fibre networks as a grid of seismic stations, training ML models across multiple nodes for improved earthquake early detection.
🚀 Why This Matters:
As optical networks become more autonomous and reconfigurable, integrating disaster monitoring capabilities could revolutionize early warning systems—saving lives and infrastructure.
